Application of dynamic decision method for automatic allocation of address in airport IoT node-device

Abstract

With the rapid development of the airport, the application of the Internet of things is becoming more and more popular. And the scale of the Internet of things (IoT) system is also becoming larger, in order to better manage and monitor all node-device in IoT system, the node-device is required to provide a unique access address. Since all node-devices are set according to the default factory address, in the early stage of the construction of the IoT system, the address of the node device needs to be modified one by one, which is with large workload, error and inefficient. In the later maintenance of the system, the address of all node-device needs to be reconfigured in different ways, which not only requires huge workload, but also needs to suspend the operation of the device. The method described in this paper, which can make each node-device configure its address by itself with dynamic intelligent address allocation strategy and in the case of not suspending the equipment, Improving the efficiency of system construction and equipment maintenance in the later stage, and also provide technical support for the construction of smart airport. The method in this paper effectively complete a series of work of automatic address allocation and modification, through the functional verification of practical application, and improve the efficiency of node-device address setting and maintenance of the IoT system in the initial and later stages of construction.
